Part Number: LM36274 Tool/software:
LM36274 Min I2C CLK freq for LM36274 is 1MHz? Only found fast mode spec min 1MHz in the datasheet.
Our design's I2C frequency now is standard mode 100KHz, LM36274 can support I2C 100KHz?
Hi Will,
May I know what is the load current on VNEG? LM36274 has a PFM mode on the charge pump, so the frequency will also be impacted by load.

Hi Jay,
Unfortunately, LM36274 only support analog dimming, if you want direct PWM dimming, LP8556 is recommended. For Bias power, I will recommend TPS65132.

Part Number: LM36274 Hi,
1.If there is issue on CLK,does LM36274 have mechanism to recover itself?
2. Will LM36274 pull SDA low to trigger CLK timeout issue?
Thanks

Part Number: LM36274 Hi Team,
here is a question on auto-switching frequency operation.
During actual test, we find that
a. when the 8-bit MSB < = Low threshold, Fsw changes to 250kHz.
b. when low threshold < the 8-bit MSB <= high threshold,…

just want to check on what's the difference between below two parameters? what does it means " device not switching pass mode" ? Thanks.

Part Number: LM36274 Hi team,
In LM36274 there is an function called active discharge. I want to know its behavior when it is enabled. When the device switches to shutdown mode, will this function enable for a long time? Or it is just used in switching…
Part Number: LM36274 Hi team,
For the VNEG short-circuit protection, I wonder how the filter works. In my understanding, I think the filter works right after the ramp finishes. The pictures are attached below. Besides, is there any relationship between…
